Comicbook.com posted some photos today from the set of James Gunn’s latest entry in the franchise, and the reveal is pretty hilarious. Fillion is revealed as an actor from Earth, whose movies are being shown in a marathon session at a movie theater back home. Included in the photo set are a rom-com, a Toxic Avenger spoof, and even a poster showing Fillion as the lead in a Tony Stark biopic — designed to look like last year’s Steve Jobs.

The real twist is that this actor’s name is Simon Williams, which deep-cut Marvel fans will know as the identity of Wonder Man. If you’re unfamiliar, that superhero starts as a super-villain who eventually joins the Avengers, and even becomes a burnt-out crimefighter who returns to civilian life as an actor. Hopefully this trajectory is reversed, and Williams the actor winds up joining the Avengers, because oh wow, do we need Nathan Fillion in that world full-time.
